Are you planning to do an IEO or the traditional ICO? I would recommend you to go for IEO's on trusted exchanges, it's very difficult to get investors if you went to the ICO route. Most investors don't see the assurance that they get from ICO compared to IEO.
IEO is now in trend, but having paid $ 300,000 for IEO, the exchange does not guarantee that you will sell all tokens
